Cleaning robot

Abstract

A cleaning robot is provided. The cleaning robot includes a body, a light detection and ranging (LiDAR) module having a LiDAR sensor rotatably supported by the body, a light-emitting display module mounted on the LiDAR module, wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module.

The invention claimed is: 
     
       1. A cleaning robot comprising:
 a body; 
 a light detection and ranging (LiDAR) module having a LiDAR sensor and rotatably supported by the body; and 
 a light-emitting display module mounted on the LiDAR module, 
 wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module, 
 wherein the light-emitting display module is mounted in an upper horizontal surface of the LiDAR module. 
 
     
     
       2. The cleaning robot of  claim 1 , further comprising:
 a plurality of light-emitting display modules. 
 
     
     
       3. The cleaning robot of  claim 2 , wherein the plurality of light-emitting display modules are arranged at equal angular intervals. 
     
     
       4. The cleaning robot of  claim 1 , wherein the LiDAR module includes an input unit for receiving an input. 
     
     
       5. The cleaning robot of  claim 4 , wherein the input unit comprises a non-contact-type sensor. 
     
     
       6. The cleaning robot of  claim 4 , wherein the input unit comprises a proximity sensor. 
     
     
       7. The cleaning robot of  claim 4 , wherein the input unit comprises an upper proximity sensor arranged in an upper portion of the LiDAR module. 
     
     
       8. The cleaning robot of  claim 7 , wherein the upper proximity sensor is arranged at a rotational center of the LiDAR module. 
     
     
       9. The cleaning robot of  claim 7 , wherein the upper proximity sensor has an angular interval with respect to the light-emitting display module. 
     
     
       10. The cleaning robot of  claim 4 , wherein the input unit comprises a side proximity sensor arranged in a side portion of the LiDAR module. 
     
     
       11. The cleaning robot of  claim 10 , wherein the side proximity sensor has an angular interval with respect to the LiDAR sensor. 
     
     
       12. The cleaning robot of  claim 10 , wherein the side proximity sensor is arranged closer to an upper portion of the LiDAR module than the LiDAR sensor. 
     
     
       13. A cleaning robot comprising:
 a body; 
 a light detection and ranging (LiDAR) module having a LiDAR sensor and rotatably supported by the body; 
 a proximity sensor mounted in the LiDAR module; and 
 a light-emitting display module mounted on an upper horizontal surface of the LiDAR module. 
 
     
     
       14. The cleaning robot of  claim 13 , wherein the proximity sensor comprises an upper proximity sensor arranged in an upper portion of the LiDAR module. 
     
     
       15. The cleaning robot of  claim 13 , wherein the proximity sensor comprises a side proximity sensor arranged in a side portion of the LiDAR module. 
     
     
       16. The cleaning robot of  claim 13 ,
 wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module. 
 
     
     
       17. The cleaning robot of  claim 16 , wherein the light-emitting display module includes a plurality of light-emitting elements. 
     
     
       18. The cleaning robot of  claim 17 , wherein the plurality of light-emitting elements each includes a light-emitting diode. 
     
     
       19. The cleaning robot of  claim 17 , wherein the plurality of light-emitting elements are arranged in a radial direction from a rotation center of the LiDAR module.
